This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled withappropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be moresusceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

Over operating free-air temperature range (unless otherwise noted).

When designing for ultralow power, choose system OVER-VOLTAGEcomponents carefully. To minimize currentconsumption, select large-value resistors. Any Input currents are typically 10pA. However, largeresistors will react with stray capacitance in the circuit inputs (greater than 500mV beyond the supply rails)and the input capacitance of the operational amplifier. can cause excessive current to flow in or out of theThese parasitic RC combinations can affect the input pins. Therefore, in addition to keeping the inputstability of the overall system. A feedback capacitor voltage between the supply rails, it is also importantmay be required to assure stability and limit to limit the input current to less than 10mA. Thisovershoot or gain peaking. limiting is easily accomplished with an input resistor,

as shown in Figure 24.Good layout practice mandates the use of a 0.1µFbypass capacitor placed closely across the supplypins.

OPA369 series op amps are fully specified and testedfrom +1.8V to +5.5V (±0.9V to ±2.75V). Parametersthat vary significantly with supply voltage are shownin the Typical Characteristic curves.

If VIN falls below VL, the output of A2 is high, currentflows through D2, and VOUT is low. Likewise, if VINFigure 26 shows the OPA2369 used as a window rises above VH, the output of A1 is high, current flowscomparator. The threshold limits are set by VH and through D1, and VOUT is low. The window comparatorVL, with VH > VL. When VIN < VH, the output of A1 is threshold voltages are set as follows:low. When VIN > VL, the output of A2 is low.

Therefore, both op amp outputs are at 0V as long asVIN is between VH and VL. This architecture results inno current flowing through either diode, Q1 in cutoff,with the base voltage at 0V, and VOUT forced high.

(1) The marketing status values are defined as follows:ACTIVE: Product device recommended for new designs.LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.PREVIEW: Device has been announced but is not in production. Samples may or may not be available.OBSOLETE: TI has discontinued the production of the device.

(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substancedo not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI mayreference these types of products as "Pb-Free".RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold.

(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.

(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuationof the previous line and the two combined represent the entire Device Marking for that device.

(6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finishvalue exceeds the maximum column width.

Resale of TI products or services with statementsdifferent from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for theassociated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements.Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designersremain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers havefull and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI productsused in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, withrespect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerousconsequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm andtake appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer willthoroughly test such applications and the functionality of such TI products as used in such applications.TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended toassist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in anyway, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resourcesolely for this purpose and subject to the terms of this Notice.TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TIproducts, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specificallydescribed in the published documentation for a particular TI Resource.Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications thatinclude the TI product(s) identified in such TI Resource.

Using products in an application does not by itself establish any safety features in the application. Designers mustensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products inlife-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., lifesupport, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, allmedical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applicationsand that proper product selection is at Designers’ own risk. Designers are solely responsible for compliance with all legal and regulatoryrequirements in connection with such selection.Designer will fully indemnify TI and its representatives against any damages, costs, losses, and/or liabilities arising out of Designer’s non-compliance with the terms and provisions of this Notice.
